Tips: How to install a threaded 3 way pneumatic ball valve?
- Remove the protective covers on both sides of the flange end of the pneumatic three-way female ball valve, and rinse and clean with the valve fully open.
- The whole machine should be tested according to the regulations before installation, and it can be installed online only after passing the test.
- Before preparing to connect with the pipeline, it is necessary to rinse and remove the remaining impurities in the clean pipeline.
- During the installation of the pneumatic three-way internal thread ball valve, please do not use the actuator part of the valve as the lifting point to avoid damage to the actuator and accessories.
- The 3 way threaded pneumatic ball valve should be installed in the horizontal or vertical direction of the pipeline.
- The pipeline near the installation point of the pneumatic three-way ball valve shall not be sagging or subjected to external force. Pipe supports or supports can be used to eliminate the deviation of the pipeline.
- After the pneumatic ball valve is connected to the pipeline, please cross-lock the flange connecting bolts with the specified torque.
